Interesting. Thank you for the test. I really do like my 4v. I think the magna cut did great for stain-less. I will be looking for some in an attractive edc folder. Thanks again. +1
I have completely changed my opinion about this steel after watching your videos. I never liked 1095 steel before because it was too brittle (in fact it is also very brittle with standard heat treatment). I watched a lot of clips on youtube about 1095 steel being as brittle as GLASS even with expensive knife brands like TOPS, ESSE... But 1095 steel with YOUR HT is very excellent. These results accurately reflect your predictions about the potential excellent performance of 1095 steel if it has a good heat-treated. 1095 steel has been on the top of my favorite steels, but only with YOUR HT.
Thanks. I will perform qualitative (semi-numerical measurement) impact toughness test comparing against conventional ht 8670 specimens. I think a quantitative/measurement would be nice but not necessary. Also impact toughness #s aren't a guarantor attribute for edge stability, often conventional high # has inverse proportional relationship to edge stability.
I wonder if you're mixing something up here. 1095 in production knives I'd rather associate with soft blades, dulling quickly but easy to resharpen. Rather rolling than chipping.
The FZ-making knives channel do crucible steels from all kinds of stuff like drill bits. I wonder how they'd perform. Let's say they'd take 1095 and add some drill bits high in Mo and V but not so much of Cr to make it soft. I was thinking of doing that with a carbon electrode and a welding machine. Going for a thin bar because I dont have an anvil or a forge for that matter. It's probably better to improvise a forge tho. A custom steel would be nice. Even CPM could be done at homo if you had or made the powders and had a press. It's expensive because we pay for their halls full of million dollar machines. The process alone is not so difficult
You severely lack understanding of how those powders are made if you think you can make them in your garage. They don't have those "halls of million dollar machines" because they're pretty... Edit: after re-reading, I'm convinced you don't understand _any_ part of the process
Most drill bits are made from hss to withstand high temperature (preserve hot hardness) by enriched with Mo & W. Atomized carbide in air would clump-up & oxidize, thus readily available in situ for home HIP. Pretend otherwise, yeah it would be fun to make a hot cylinder/box + water piston then HIP with a 300 Magnum :p
@@BluntCutMetalWorks You are probably right that I dont understand the process fully. I havent researched it much beyond this video: th-cam.com/video/MgukjCT9o80/w-d-xo.html Your article seems to make it more difficult than it is. In the video you get the powders, you blend them in desired ratio along with a binder (resin, flux?) and you shape it in a press mold. Then you cook it and heat treat to costumer needs. IMHO you dont need to spray hot metal through nitrogen to atomize it. There's an electro-chemical way to get pure metal powder that precipitate on cathode from acid solution. The process is known at least since 1947 in Soviet Union.

It's not that hard to play with and if it is, there are metallic powders on the market. I'm telling you, the fancy steels they make are easy to reproduce but companies cant because of the patents. We pay for the research too. It's ok I guess but we pay enough to make them billion dollar monopolies. What I'm trying to say is If you know the composition, not to mention the ideal heat treatment, you should be able to do it at home for a fraction of the cost. I believe it's possible.
1095 capable of repeated/compounded chops, whereas alloyed steels blade would chip readily on subsequent chops because their work-hardened state incline toward crack nucleation

You should be getting more views on these! Great work!
Please describe your heat treatment for 1095. Very interesting.
The 1095 did well. 👍

Indeed, Magnacut performed well as a stainless. EDC sure doesn't need this level of toughness anyway.

You must be on something if you think 1095 is brittle, do you even know what 1095 is?
@saiiiiiii1 yeah he's got to be confused
I have like 5 blades in 1095 and they're crazy tough, but I have to sharpen some of them often with use.
Your HT for 1095 is amazing , did you do multiple cryo etc ?
Wich HRC ?
Yes, I did utilized LN2 however not conventionally. Hrc 60, keep in mind hrc can play small part in edge strength.

Agreed, PM processes required very expensive setup.
